Precision Twist Drill 5010676 Hss Chucking Reamer 7/16 in

Product Description

The PRECISION TWIST DRILL 5010676 is a high-speed steel (HSS) chucking reamer with a straight flute design, built for precision hole finishing in metal, plastic, and composite materials. With a 7/16 inch diameter tip and an overall length of 7 inches, this reamer is sized for common chucking applications where a tight, accurate bore is required. Machinists and trade professionals use chucking reamers to bring a drilled hole to a precise final diameter with a clean surface finish. The HSS construction provides durability and heat resistance suitable for production and maintenance environments.

This reamer is intended for use in drill presses, lathes, and milling machines where the tool is held in a chuck and driven at controlled speed and feed. Typical applications include finishing holes in steel, aluminum, brass, and similar materials to close tolerances. The straight flute geometry makes it well suited for through-holes and short blind holes where chip clearance is manageable. It is sold as an individual piece, making it a practical replacement or addition to a machinist or maintenance technician tool set.

Key Features

• High-speed steel (HSS) construction for heat and wear resistance
• Straight flute design suited for through-holes and short blind holes
• 7/16 inch diameter tip for consistent, accurate final bore sizing
• 7 inch overall length for reach in standard chucking setups
• Chucking reamer style — compatible with drill press, lathe, and milling machine chucks

Compatibility

Designed as an OEM-style chucking reamer for use in standard drill press, lathe, or milling machine chuck setups requiring a 7/16 inch finished bore diameter.

Installation Notes

Chucking reamers are installed and operated by machinists and maintenance technicians using a drill press, lathe, or milling machine. Always secure the workpiece and power down the machine before changing tooling. Run reamers at lower RPM than drill bits for the same material, and use cutting fluid appropriate to the workpiece material to extend tool life and improve finish quality. Follow applicable shop safety standards and machine manufacturer guidelines during setup and operation.
